Articles for magazine about virtual surroundings

Need a writer for about 5 articles for a magazine about virtual worlds, the techniques behind them, realisations, how it will change the digital publishing etc. Two of the five can be a compilation of earlier publishings on the web, the other three will be about companies (we deliver the names and contacts of the companies). You can send them a list with questions, they will answer the questions and you have to make the article. Each article will be about 400 - 600 words. Your offer will be for these 5 articles, but if you deliver a good job, you will be asked for the next editions (every two months) Only offers with an example of your work will be accepted.
